Abstract:
The caries-preventive effect of glass-ionomer sealant depends on both retention of sealant and fluoride release. In this study, the retention rate was maintained by sealant reapplication over three years. Caries reduction was 76.1 percent at one year, 69.9 percent at two years and 66.5 percent at three years. Reapplication is an acceptable procedure and seemed to improve caries reduction.
